2. 1. Reconfigurable Receiver Front-Ends for Advanced Telecommunication Technologies

   Author : Iman Ghotbi; Integrerade elektroniksystem; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 5G; Receiver; Filter; Low-noise amplifier; FD-SOI; Calibration;

   Abstract : The exponential growth of converging technologies, including augmented reality, autonomous vehicles, machine-to-machine and machine-to-human interactions, biomedical and environmental sensory systems, and artificial intelligence, is driving the need for robust infrastructural systems capable of handling vast data volumes between end users and service providers. This demand has prompted a significant evolution in wireless communication, with 5G and subsequent generations requiring exponentially improved spectral and energy efficiency compared to their predecessors.

4. 2. On Enhancement and Quality Assessment of Audio and Video in Communication Systems

   Author : Andreas Rossholm; Blekinge Tekniska Högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; QoE; video quality assessment; video quality metric; multi-linear regression; artificial neural network; support vector machine; quality predictor; machine learning; temporal scaling; spatial scaling; video compression; deblocking filter; noise cancelling; synchronization; audio delay; video delay; GSM interference signal; noise cancellation; notch filtering;

   Abstract : The use of audio and video communication has increased exponentially over the last decade and has gone from speech over GSM to HD resolution video conference between continents on mobile devices. As the use becomes more widespread the interest in delivering high quality media increases even on devices with limited resources. READ MORE

5. 3. Some studies on metamaterial transmission lines and their applications

   Author : Xin Hu; Sailing He; Ferran Martin; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metamaterial; transmission line theory; composite right left-handed transmission line; diplexer; coupler; balun; interdigital capacitor; split ring resonator; Electrical engineering; Elektroteknik;

   Abstract : This thesis focuses mostly on investigating different potential applications of meta-transmission line (TL), particularly composite right/left handed (CRLH) TL, and analyzing some new phenomena and applications of meta-TL, mostly left-handed (LH) TL. Realization principle will also be studied. READ MORE

6. 4. Electrified Integrated Kinetic Energy Storage

   Author : Magnus Hedlund; Hans Bernhoff; Markus Mueller; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flywheel energy storage; magnetic bearings; carbon composite; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Abstract : The electric car is a technically efficient driveline, although it is demanding in terms of the primary energy source. Most trips are below 50 km and the mean power required for maintaining speed is quite low, but the system has to be able to both provide long range and high maximum power for acceleration. READ MORE

7. 5. Reconfigurable and transparent wavelength division multiplexed optical transport networks

   Author : Erland Almström; KTH; []
   Keywords : ;

   Abstract : This thesis is about reconfigurable and transparentwavelength division multiplexed (WDM) networks.Reconfigurability is used to achieve higher surveillance andthroughput in the network. This is done by wavelength selectiveand independent network elements. These network elements canaccomplish bypass and protection switching ofthe traffic. READ MORE
